AR 2832 in CaK.

Post by torsinadoc »

Trying to get caught up on processing. This was taken 6/11

102 F11 achromat (canadian telescope version) masked to 80 + Lunt 1800 CaK Double stack
Celestron Luminos 2.5x and Basler 155
Processed in AS3, Pixinsight, IMPPG

I really like this scope for Calcium.

Very nice resolution! That's one thing I love about narrowband solar imaging. A quality achromat can hold it's own against an apochromat! Achromats are so much more affordable and underrated these days.

I agree. I really like this cheap achromat for Ha and CaK.

Very impressive indeed. Achromats are the way to go with solar.

It would be interesting to see the difference between the 80mm f14 and the 102 f11 performance in CaK.
I’ve just moved from a 60 f10 setup to a Vixen Custom 80M (made in Japan) 80 f11.4 and find the results well worth while. I think any system >f10 is good news for the CaK filter.

I will test it the next time conditions allow (60,80,102)

I looked pretty hard at the Vixen 80/F11.4 achromat

I had to change the focuser to a 2” to accommodate the CaK filter.
I also added a SW focuser motor
